Hello guys
Is there any way to check if downloaded image(.TIFF,.PNG,.JPEG and others) has compression or not ?
Currently I'm using OpenCV, but I don't care how to retrieve this info.
If I open some image via ordinary Windows Explorer->Right button click->Properties->Details->and we all can see a "compression" field
Thnx

Almost all image file formats have a header section. The header section often has a field that indicates whether compression has been used or not, and if so what particular method.
I suggest finding a library that can handle different file formats and the exposes this information to you, otherwise you'll have to roll your own file reader that will have to recognize various files.
